I love that this type of light shows up so early in the afternoon this time of year.
I let a friend borrow my Fuji X100s over the weekend for a concert he was shooting and in return, he lent me his Olympus Zuiko 55mm, f/1.2. I've never used a lens with such a large aperture and it really is just a completely different experience.
The backgrounds are incredibly textured and swirly which can give a nice emphasis to foreground elements. I think you'd need to be really careful that the background doesn't distract from the intended subject though.
As you can learn quite easily from a quick google search (and these photos), this lens is fairly soft at the maximum f/1.2 aperture, but there is a dream-like effect you receive in exchange. If you are looking for a sharper image it's just one click over to f/2.
The glass in this lens is enormous which you can see in my selfie here or John Carey's desktop featuring another copy of the same lens.
Overall, this is a really unique piece of gear. Like pretty much any lens with a big aperture, it does stuff that your standard lens can't pull off. I'm not sure I need one, but it sure is fun!
I haven't posted a desktop in awhile, but I want this one on my own screens. If you click the link to download the iPad version, you'll probably notice that it's actually a different image. The larger one didn't crop quite right, but I had another that did.
To download and use these, just click on the link below the image and then save it. The Mobile iOS versions are sized to work with the Parallax feature. If you're using an iPhone 6 or older, then you'll need to pinch and drag to set it how you like it. Thanks to John Carey for doing the research.
Also, I just updated the desktop version and it is now compatible with the 5k iMac.
